Each DreamWorks Trolls Pom-Poms keychain contains a small surprise doll that can be flipped over to be revealed. The plush pom-pom transforms into a beloved Trolls character with the signature colorful hair. The Rainbow Series is inspired by the DreamWorks film "Trolls World Tour." It is the first series in the collection featuring six popular characters that children can collect. Simply attach them to backpacks or other straps, and they can be displayed and taken along. All items are sold separately. The dolls cannot stand on their own. Color and design may vary.
